The answer is all of them.
getting criticized for your stance
meeting unscrupulous people
learning about how a campaign works
learning all there is to know about a candidate
voting the long ballot in an election

Getting involved in politics basically announce to the world the set of principles that you held in your mind, and make several efforts to promote/choose the representative that fit your principles,
Some people would definitely held different view than yours, which often led to criticism or even blatant mockery.

It's most likely choice a, it makes the most sense in my opinion.
